To all whom t may concern.'

Be it known that we, TONY HOFF, LAN

at Butte, in the county of Silver Bow and' State of Montana, have invented new and l which the following is -a specification.

' This invention relates to improvements in riveting tools, the general object of the in-V vention being to provide a tool which is formed of several parts so arranged that the outer parts will take the shock of the blow so that the head 0f the tool will remain on kthe rivet. readyfor the next blow and no time islost in replacing the tool.

Another object of the invention is to'make the head of the tool detachable and to provide/different sizes of heads so that the tool can lbe used in connection with different Y sizes of rivets.

and specifically pointed out in the appendedl claim. .y

Tn describing the invention in detail, reference will be had to Ythe accompanying drawings wherein like characters y denote like or corresponding-parts throughout' the several views, and in which Figure 1 is an elevation of the invention.

Figure 2'is a longitudinal sectional view.

Figure 3 is a view of the head 5.

Figure 4 is a transverse sectional view.

In these views 1 indicates the body of the tool which is provided with enlarged ends and a reduced center to Yform a handle. This body is solid at one end and has a socket 2 which passes through its other end. The face of the solid end is provided with an under cut groove 3 to receive a tongue L1 on the head This head` is of tapered shape, as shown, land is provided with an in?- dentation 6 for receivingthe bottom of the rivet. The inner end of the head is pro-y vided with a screw threaded socket 7 for Vreceiving the screw threaded end of a rod 8, said rod passing through an opening made in the solid part of the body and which Opens out into the socket 2. Thistrod 8 is of greater length than the body and it Thus the toolis in position4 is provided withga reduced part 10 adjacent its outer end. An absorber block 11 is threaded over the rod'S and rests in the socket 2 of the body with one end engaging the bottom offthe socket. The corners of this block are beveled, as shown, if desired several of these blocks may be used. A bar 12 has a' bore 13 in one end for receiving the rod 8 and said bar isfslidingly secured to said rod by means of a pin 14 which passesv Vthrough a hole in the bar 12 and passes through the annular space formed by the reduced part 10 of the rod 8 and bore 13. This arrangement of partspermits the bar 12 tok have rotary movement on the-rod as well as a limited sliding movement. This bar 12, has a part fitting in the socket 2 so Y that one end will bear against `the block 1l,

said end being beveled, as shown. The outer end-of the'bar 12 is enlarged and rounded to t theV shown at 15.

palm of the hand, as

The Yparts areassembled by sliding the tongue of the headin the groove 3 of the body. and then passing the rod 8 through the' hole and steeringl it into the'socket 7. This will secure the head to the body.y The block 11 is theny placed over the rod vand then the bar 12 is put in place and fastened by the pin 14 which may be screw threaded to engage the-screw threaded hole in the bar 12. The body is held in one hand with the indentation 6 in the head against the bottom yof the rivet andl the bar 12 hasit-send held in the palm of the other hand. The shock of the blows on the rivets will be taken by this bar 12 and the block 11 which are movably attached to the body.' Thus the head will remain on the rivet so that no time is lost in replacing the head'and preventing improper riveting bythe block not being in the proper place. By makingthe head detachable different sizes of heads vmay be used with the toolto suit the differtion that the` advantages and novel features f of the invention will be readily apparent.

lVe ydesire it to be understood that we may make changes in theconstruction and in the f combination and arrangement of the several ing; screw threaded connection with the head 10 parte, provided that Such changes fell Withend passing through the bodyl and upon in the scope of the appended Claim. which the block and handle are placed.
